Mandevilla plant named &#39;BBYEL&#39;

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘BBYEL’, characterized by its upright and vining plant habit; moderately vigorous growth habit; freely branching habit; moderately glossy dark green-colored leaves; freely flowering habit; and bright yellow-colored flowers.

Botanical designation: Mandevilla sanderi.

Cultivar denomination: ‘BBYEL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofMandevilla plant, botanically known as Mandevilla sanderi andhereinafter referred to by the name ‘BBYEL’.

The new Mandevilla plant is a product of a planned breeding programconducted by the Inventor in De Kwakel, The Netherlands.

The objective of the breeding program is to create vining Mandevillaplants with unique and attractive flowers.

The new Mandevilla plant originated from a cross-pollination conductedby the Inventor in De Kwakel, The Netherlands in May, 2013 of aproprietary selection of Mandevilla sanderi identified as code numberBC13-324, not patented, as the female, or seed parent with a proprietaryselection of Mandevilla sanderi identified as code number BC12-015, notpatented, as the male, or pollen, parent. The new Mandevilla plant wasdiscovered and selected by the Inventor as a single flowering plant fromwithin the progeny of the stated cross-pollination in a controlledgreenhouse environment in De Kwakel, The Netherlands in August, 2014.

Asexual reproduction of the new Mandevilla plant by cuttings in acontrolled greenhouse environment in De Kwakel, The Netherlands, sinceOctober, 2014 has shown that the unique features of this new Mandevillaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘BBYEL’. These characteristics incombination distinguish ‘BBYEL’ as a new and distinct Mandevilla plant:

-   -   1. Upright and vining plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Moderately glossy dark green-colored leaves.    -   5. Freely flowering habit.    -   6. Bright yellow-colored flowers.

Plants of the new Mandevilla can be compared to plants of the femaleparent selection. Plants of the new Mandevilla differ primarily fromplants of the female parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Mandevilla are smaller with more        pointed apices than leaves of plants of the female parent        selection.    -   2. Plants of the new Mandevilla and the female parent selection        differ in flower color as plants of the female parent selection        have pale yellow-colored flowers.

Plants of the new Mandevilla can be compared to plants of the maleparent selection. Plants of the new Mandevilla differ primarily fromplants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are not as compact as plants of        the male parent selection.    -   2. Plants of the new Mandevilla have smaller flowers than plants        of the male parent selection.    -   3. Plants of the new Mandevilla and the male parent selection        differ in flower color as plants of the male parent selection        have pale yellow-colored flowers.

Plants of the new Mandevilla can be compared to plants of Mandevillasanderi ‘Lancalifornia’, disclosed in U.S. Plant Pat. No. 24,074. Inside-by-side comparisons, plants of the new Mandevilla differ primarilyfrom plants ‘Lancalifornia’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are upright and vining in plant        habit whereas plants of ‘Lancalifornia’ are upright to outwardly        spreading in plant habit.    -   2. Leaves of plants of the new Mandevilla are smaller with more        pointed apices than leaves of plants of ‘Lancalifornia’.    -   3. Plants of the new Mandevilla have smaller flowers than plants        of ‘Lancalifornia’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the late spring and early summerin 17-cm containers in a glass-covered greenhouse in De Kwakel, TheNetherlands and under cultural practices typical of Mandevillacommercial production. During the production of the plants, daytemperatures ranged from 16° C. to 25° C. and night temperatures rangedfrom 16° C. to 20° C. Plants were ten months old when the photographsand description were taken.
